Re: Re: Vitamin D - Yet Again

[Guest guest]

The good news is that vit D is fat soluble so the body does store some to

carry us through periods of low/no sunlight. That said it appears many still

don't get enough... seems to me that mid winter visits to So. Florida should

be valid medical deductions :-)

So, I take vit. D from fish liver oil. Is there a

healthier source given that I live too far north

to obtain adequate supplies from sunlight for

several months of the year.

Sunlamp, perhaps?

Pill vit D is not the same, unless prescription.

Regards.

Vit D is added to milk, and can be ingested from food by eating fish

(sardines, salmon) . We have a link to dietary sources IIRC. If you don't

overdo with the fish liver oil you should be Ok. When I supplement, I use

GNC's Vit D (which is not from fish liver oil) and I'm sure other Vit D's

can be found on the web.

It's a good idea even if you live far north to get out during the sunny

parts of the day. Daylight exposure has other benefits.

For me a sunlamp (offering highest level of UBV w/out prescription) did not

work. Whereas 15 min 3 x wk in sun did work ( in summer months)

The following seems to agree with you:

Vitamin d2 is much less effective than vitamin d3 in humans.

Armas LA, Hollis BW, Heaney RP.

Creighton University, 601 North 30th Street, Suite 4841, Omaha, Nebraska

68131. rheaney@....

Vitamins D(2) and D(3) are generally considered to be equivalent in humans.

Nevertheless, physicians commonly report equivocal responses to seemingly

large doses of the only high-dose calciferol (vitamin D(2)) available in

the U.S. market.The relative potencies of vitamins D(2) and D(3) were evaluated

by administering single doses of 50,000 IU of the respective calciferols

to 20 healthy male volunteers, following the time course of serum vitamin

D and 25-hydroxyvitamin D (25OHD) over a period of 28 d and measuring the

area under the curve of the rise in 25OHD above baseline.The two calciferols

produced similar rises in serum concentration of the administered vitamin,

indicating equivalent absorption. Both produced similar initial rises in

serum 25OHD over the first 3 d, but 25OHD continued to rise in the D(3)-treated

subjects, peaking at 14 d, whereas serum 25OHD fell rapidly in the D(2)-treated

subjects and was not different from baseline at 14 d. Area under the curve

(AUC) to d 28 was 60.2 ng.d/ml (150.5 nmol.d/liter) for vitamin D(2) and

204.7 (511.8) for vitamin D(3) (P < 0.002). Calculated AUC(infinity) indicated

an even greater differential, with the relative potencies for D(3)(2) being

9.5:1.Vitamin D(2) potency is less than one third that of vitamin D(3). Physicians

resorting to use of vitamin D(2) should be aware of its markedly lower potency

and shorter duration of action relative to vitamin D(3).

It seems to me that d is stored in fat within liver. Perhaps then that

a low fatty liver has less room to store it. Just a thought.

[Guest guest]

Yes it was me.... but others may be different. OTC supps for D didn't

work for me. Sunlamp didn't work for me Sun in the summer did work. I

don't have tests from D3. I tried cod liver oil, but stopped b/c I

worried about too much zinc & A. I agree w/Francesca that cod liver oil

is probably OK if you don't over do it. I suspect cod liver oil works.
